vfquery

Mapdl.vfquery(srcelem='', tarelem='', **kwargs)

Queries and prints element Hemicube view factors and average view

APDL Command: VFQUERY factor.

Parameters
  • srcelem – Elements representing the source radiating surfaces used to query the view factor at the target element(s). If SRCELEM = P, graphical picking is enabled (valid only in the GUI). If SRCELEM = ALL, all selected elements will have their view factors queried. A component name may also be substituted for SRCELEM. Selected elements must be flagged for surface to surface radiation in order to query view factors (SF, SFA, or SFE with Lab = RDSF). The view factors must have been previously computed.

  • tarelem – Element for view factor query. If TARELEM = P, graphical picking is enabled (valid only in the GUI). If TARELEM = ALL, all selected elements will have their view factors queried. A component name may also be substituted for TARELEM. Selected elements must be flagged for surface to surface radiation in order to query view factors (SF, SFA, or SFE with Lab = RDSF). The view factors must have been previously computed.

Notes

View factors for each target element will be printed.

An average view factor for all target elements will be computed. (Use *GET to retrieve the average value).
